Abstract (en)
[origin: EP0404491A2] A piezoelectric transducer (PZT) device (104) operating at a relatively high frequency is coupled to an imaging surface to cause localized vibration of predetermined amplitude, and is positioned in close association with a cleaning enhancing electrostatic charging or discharging device (102, 200) associated with the imaging surface cleaning function, whereby residual toner and debris is fluidized for enhanced electrostatic discharge of the toner and/or imaging surface, and released from the mechanical forces adhering the toner to the imaging surface.
